WILLIAM H. BATES, OF JACKSON, MICHIGAN, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE JACKSON CUSHION SPRING COMPANY, OF SAME PLACE.

CUSHION-SPRING AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 683,428, dated. October 1, 1901. Application filed September 1, 1900. Serial No. 28 799. (No modeli) To all whom it may concern.-

Be it known that I, WILLIAM H. BATES, a citizen of the United States, residing at the city of Jackson, in the county of Jackson and 5 State of Michigan, have in vented certain new and useful Improvements in Cushion-Springs and Supports; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled m in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to spring-seats in general, although the principles involved may be applied to mattresses and backs, and

.it has specific reference to the construction of the springs and their retaining means, the

object of the invention being to provide a cheap, simple, and efficient construction wherein the springs will be held firmly in their operative positions and wherein they may be readily applied and removed when 2 5 occasion may require, further objects and advantages being evident from the following description.

In the drawings forming a part of this specification, and in which like numerals of 0 reference indicate similarparts in the several views, Figure 1 is a top plan view showing a seat with the cover removed to show the frame and the arrangement of the springs and their supporting means. Fig. 2 is a section on the 5 line 2 2 of Fig. 1 and showing the engagement of the hooks of the springs with the bends of the supporting-wires. Fig. 3 isa perspective view showing the supporting-wires and staywires connected. Fig. 4 is a perspective view 0 showing a modification wherein eyes or loops are formed on the supporting-wires for engagement by the hooks of the springs. Fig. 5 is a view similar to Fig. 2 and showing a construction wherein the hooks are formed 5 upon the supporting-wires and the eyes on the springs. Fig. 6 is a view similar to Fig. 3, showing a construction in which the sup porting-wires and stay.wires are permanently fastened together. Fig. 7 is a perspective view of the double springs, parts being broken away. Fig. 8 is a top plan view of the springs, the upper portion thereof being broken away.

' Referring now to the drawings, the seat is formed upon a frame including end pieces 5 and 6 and side pieces 7 and 8, and secured to the end pieces are supporting-wires 9, which have their ends bent upwardly and sharpened and driven into the under sides-of the end pieces 5 and 6. Stay-wires 10 are disposed beneath the supporting-wires and have their ends downwardly bent and driven into the upper edges of the side pieces 7 and 8, the stay-wires where they cross the supportingwires having downwardly-directed bends 11 formed therein,'which bends receive the bends 6 of the supporting-wires, the opening of the bends being contracted, so as to spring over the supporting-wires, and, f urthermore,when the supporting-wires are depressed the staywires are bent, so that the openings of the bends are brought narrower, and thus hold the supporting-wires more firmly against dis placement. The supporting-wires and staywires may be connected together in any other suitable manner. For instance, they may be permanently connected together by the wire 30, as shown in Fig. 6, and in this manner may be permanently connected to be shipped ready to attach to the frame.

The supporting-Wires 9 have upwardly-di- 8o rected bends 12 formed therein and properly spaced, the openings therein being also contracted, as shown.

The springs 13 employed are formed in pairs from a single piece of wire 14 and are each convolute and conical, the end of the wire at the lower minor end of the spring being taken upwardly on a slant and above the lower convolution 15, which it crosses, after which it is turned laterally to extend diametrically of the convolution and is then bent to form a hook 16, passing through the axis of the spring and at right angles to the plane of the minor convolution. The bill of the hook is in the form of a compound curve to form a hump 5 17, as shown, the bill being disposed above the lower or minor convolution of the spring, whereby when said hook is engaged with a bend 12 of the supporting-wire said bend will project upwardly into the spring and the mo wire will be held tightly against the bottom or minor convolution of the spring, the hook being so positioned that the supporting-wire will lie in the angle where the inturned end of the wire 14 crosses the bottom convolution, the spring being compressed to permit this engagement of thehook with the bend. Thus when the spring is released from the compression the spring is held firmly to the supporting-wire, but the spring does not tend to loosen in use, for the season that in the engagement of the hook with the bend the wire within the inclosure of thesprin g is alone distorted with relation to that portion of the lower convolution directly adjacent thereto.

As shown in Fig. 5 of the drawings, the hook may be formed in the supporting-wire, as indicated at 20, and the spring have an eye 21 for engagement therewith; also, instead of driving the ends of the supporting and stay wires into the frame they may have terminal eyes 22 engaged by attaching them by means of screws or nails 23.

In Fig. 4 of the drawings there is shown a construction wherein, instead of bends, eyes 25 are formed in the supporting-wires for engagement by the hooks ot' the springs.

What is claimed is 1. In a device of the class described, the combination with supporting-wires having deflected portions therein, of stay-wires arranged in series crossing the supportingwires and having likewise deflected portions, the deflected portions in one of said sets of wires consisting of loops with contracted mouths whereby the deflected portions of the other set may be sprung into said loops, and springs connected with said supporting-wires.

2. In a device of the class described, the combination with supporting-wires arranged in pairs and having deflected portions therein, stay-wires arranged in series crossing the supporting wires and having likewise deflected portions, the deflected portions in one of said sets of wires consisting of loops with contracted mouths whereby the deflected portions of the other set may be sprung into said loops, and conical convolute springs connected with said supporting-wires.

3. In a device of the class described, the combination with supporting-wires having upwardly-deflected portionsorloends therein, stay-wires crossing the supporting-wires and having downwardly deflected portions or bends, the portions or bends on one set of wires consisting of loops with contracted mouths adapted to be sprung int-o engagemept with the bends of the other set of wires,

and conical convolute springs terminating at their lower ends'each in a compound curve for engagement with the supporting-wires.

4. In a device of the class described, the combination with a frame, of parallel supporting-wires having their ends turned upwardly and engaging the under side of the frame, parallel stay-wires passed beneath the supporting=wires at right angles thereto and having their extremities bent downwardly and engaged with the top of the frame, the

staywires having downwardly directed bends which receive the supporting wires, and springs carried by the supporting-wires, substantially as described.

5. In combination, the frame, the parallel supporting-wires having deflected portions or bends, the parallel stay or drop wires arranged at right angles to the supportingwires and having deflected portions or bends interlocking with the bends of the supporting-wires, and springs seated on the supporting-wires independent of the stay or drop wires, substantially as described.

6. In a device of the class described, the combination with supporting-wires having upwardly-deflected bends therein, stay-Wires crossing the supporting -wires and having downwardly-directed bends, the bends of one set of wires being of loop shape with contracted mouths whereby the wires are adapted to be sprung together, and springs connected with the supporting-Wires, substantially as described.

7. In combination, a frame, parallel staywires having their endsconnected therewith and having downwardly-directed bends of loop shape with contracted mouths, supporting-wires resting in the bonds of the staywires and retained therein by the contracted mouths, and springs supported by the wires, substantially as described.

8. In combination with a supporting-Wire having an upward bend, a coiled spring having its lower coil or convolution resting-upon said supporting-wire, the end of the wire of which said spring is composed being formed into a hook which extends transversely above the lower coil and engages the said upward bend of the supporting-wire, substantially as described.-

In testimony whereof I have affixed my sig nature" in the presence of two witnesses.
